I'm at 12/62 with the 4.5. My first race. I warmed up for about 2 mins, then I ran for 8mins and finished 4th out of 15. Everybody said mine looked planted. For the next 15mins 7 people drove it and I stood and watched. It never hit the lvc. I was super excited with the run time and power it had. I would like to see my temps a little lower, but what I'm getting is fine.
